It is very true. Growing up in a broken family carries an emotional load that is too intense. My nephew is proof of this, at age 7 he has been in the middle of the discussions of my brother and his ex and that affects him, for example he knows there are things that it is better not to tell his father what he did with his mother and vice versa because he knows that this can generate friction between the parties. Hopefully we were more mature and we know how to take our relationships, for us and above all for the wellbeing of our children.
